STEP 12. Check the wiring harness between defogger relay connector C-
201 (terminal 4) and defogger connector F-01 (terminal 1).
NOTE: Also check junction block connector F-03 and junction
block connector C-204 for loose, corroded, or damaged
terminals, or terminals pushed back in the connector. If
intermediate connector F-03 or junction block
connector C-204 is damaged, repair or replace the
connector as described in HARNESS CONNECTOR
INSPECTION

STEP 16. Check the defogger.
1. Let the engine run at 2,000 r/min, and check the printed heater with the
battery fully charged.
2. Turn on the defogger switch, and use a voltmeter to measure the voltage in
each printed heater at middle point A on the rear window glass.
The value should be approximately 6 volts.
Q: Does the defogger work normally?
